A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping. 1. A bedding or seating product comprising:a pocketed spring assembly comprising a plurality of parallel strings of springs joined together to form a pocketed spring assembly core;a dimensionally stabilizing substrate secured to one of top and bottom surfaces of the pocketed spring assembly core to create a pocketed spring assembly, said dimensionally stabilizing substrate comprising a sheet being made from a continuous filament, needled polyester with a resin binder;a scrim sheet secured to the other of the top and bottom surfaces of said at least some of the strings of the pocketed spring assembly, wherein said dimensionally stabilizing substrate has a density at least twice the density of the scrim sheet and is more rigid than the scrim sheet;cushioning materials; andan upholstered covering encasing said pocketed spring assembly and cushioning materials.2. A bedding or seating product comprising:a pocketed spring assembly comprising a plurality of parallel strings of springs joined together to form a pocketed spring assembly core;a dimensionally stabilizing substrate secured to one of top and bottom surfaces of the pocketed spring assembly core to create a pocketed spring assembly, said dimensionally stabilizing substrate comprising a sheet having a weight of at least two ounces per square yard;a scrim sheet secured to the other ...
